If you are already in the Ubuntu, you can change the boot order by using Grub Customizer.

Just install it by typing this command in Ubuntu terminal:

sudo apt-get install grub-customizer

This Grub Customizer has a Graphical User Interface. Once you open the program in Ubuntu, there would be some option to set the computer boot order.


In case of you face some more problem, you can read more possible solutions from:
